Clean the balance with the hairspring attached, set on the main plate if you use a cleaning machine. Then, once the movement is reassembled and runs,  disassemble the balance and the cup jewels, clean the cup jewels, oils, and reassemble; do samething for the lower balance jewels. This is the way i do it.

With old-style cap jewels, I find the main thing to watch out for, and the main reason i've caused damage to older watches as I've learned, is slipping while loosening the hairspring stud screw and stabbing the hairspring in the heart...

 

...on the plus side, you get to re-shape the hairspring then, and that's character-building.

Good advice and lesson learned.

      Pin pallet lubrication

      By Waggy · Posted

      What works for me (waiting for the villagers to assemble with torches and pitchforks) is to put a liberal (in watch terms) spot of 9010 on one of the pins of the pin pallet, this seems to improve amplitude and beat error.

      Non-magnetic is a poor description of such a hairspring. A better description would be unmagnetisable hairspring. There are metals and alloys that are attracted to magnets, but don’t become magnetised themselves. A hairspring made out such a material will be attracted to magnetised tweezers, but will not become magnetised. These hairsprings can be disrupted by being in close proximity to a magnet, but the disruption will cease the moment the magnet is moved away. These are hairsprings that could conceivably be disrupted by a magnetised hairspring stud. Best Regards, Mark

      More than enough. Here's mine at the height I work at. I think the working distance with the included 0.5x Barlow lens is about 9".   So yes, that halves the magnification. The full story is the objective lens goes from 0.7x to 4.5x. The eyepieces are 10x, giving you the advertised magnification of 7x-45x. However the working distance is unacceptably short, so it comes with an 0.5x Barlow lens, reducing the magnification range to 3.5x-22.5x, but giving you a good working distance. What I did was buy a pair of Extreme Widefield 20x Eyepieces for when I need more magnification. You keep your high working distance, but get your 45x magnification back, at the cost of some width of field.

      Modern ones after blue steel, invar, elinvar and nivarox , the shiny one are not supposed to become magnetised. But i have had them jump to tweezers. And i dont really understand the comment that what can be magnetised is the stud carrier and rate regulator and they can attract the hairspring ? If the hairspring is non magnetic then how can it be attracted to something else thats become magnetise, its non magnetic , that doesn't really make sense to be ?

      Does it say 17 jewels on the dial or on the movement ?
